Would that be Akatere Woolcraft at Taupo Bay on the East Coast? They used to custom card and dye fleeces and also had already spun wool for sale. Ralph and Marion Logie owned it, and Ralph was the most amazing dyer ever. The only other wool shop we had was in town and was just your ordinary old wool shop. Now there is some cheap acrylic at the Warehouse and a very limited selection of baby wool and a little double knitting at the remains of the material shop.
I say remains because there is very little of anything in it.

mmm...I think I remember a shop in the Plaza in town that sold some of Ralphs wool, may be that is where you went, but gosh, that would beat least 10 years ago!
